CAR-BRAKE.

SPECIFICATION forming part of Letters Patent No. 364,706, dated June14-, 1887.

Application filed August 25, 1886. Serial No. 211,845). (No model.)

To all whom, it may concern.-

Be it known that I, BENJAMIN F. ORow, a citizen of the United States,residing at the city of St. Louis, in the State of Missouri, haveinvented a certain new and useful Improvement in Oar-Brakes, of whichthe following is a full, clear, and exact description, reference beinghad to the accompanying drawings, forming part of this specification, inwhich Figure 1 is a bottom view of the runninggear of a cable-grip carwith my improvement applied. Fig. 2' is aside elevation of same. Fig. 3is an enlarged detail perspective view, showing the connection betweenone of the 1 brake-levers and its rock-shaft. Fig. 4: is a detailenlarged perspective view of one of the adjustable rods or arms. Fig. 5is an enlarged perspective view of one of the shoes. Fig. 6 is anenlarged perspective view of one of the brackets for connecting theshoesto the frame of the running-gear. Fig. 7 is a vertical longitudinalsection taken on line 7 7, Fig. 1. Fig. 8 is an elevation of twocar-wheels, showing the shaft in section.

My invention relates to certain improvements in brakes intended moreparticularly for street and cable cars, but which may be applied toother cars; and my invention consists in features of novelty hereinafterfully 0 described, and pointed out in the claims.

Referring to the drawings, A represents the running-gear of a grip-carof a cable railway.

A represents the shoes formed and suspended by rods A and bracket A inthe same manner as shown, described, and claimed in my application filedon same date herewith, and which needs no further description here.

The brakes are applied by power received from one of the car-axles, andthis power is transmitted from the axle by means of mechanism shown anddescribed in Letters Patent of the United States No. 263,529, issuedto'Tom L. Johnson, August 29, 1882. As no invention is herein claimed onthis method of transmitting the power from the axle to the shoes, and asthis method is described in the patent referred to, no furtherdescription is given herein.

B D represent the pull-rods, connected at their inner ends by a bar, 13,which is made fast to the sleeve on the axle by means of a flexibleconnection, 13. The outer end of one of the rods B is connected to alever, O, pivoted at O to the frame of the running-gear. The outer endof the other arm is secured to 5 one end of a lever, D, the lever beingconnected at D to a clip, D as shown in Figs. 1,

2, and 3. The clip is made fast at E to one arm of a bell-crank lever,E, secured to a rock-shaft, F, that is journaled to the frame of therunning-gear by brackets G. Secured to the rock-shaft F are also arms H,made fast to the brake-shoes A, preferably by adjustable rods or arms I,as in my application above re ferred to. It-will thus be seen that whenthe 6 5 lever D is pulled by the axle, it will rock the shaft F and,through means of the arms H and connectingrod I, force the brake-shoesagainst the wheels. When the pressure is released,the brake-shoes arewithdrawn from the wheels by means of a spring, J, connected to theframe of the running-gear and to the end of the arm E by means of aclip, K. This applies the brake at one end of the car. At the other endof the car it'is applied by the lever 7 D and a rod, N, which areconnected to an arm, M, on a rock-shaft, M. The shoes at this end of thecar are connected to arms 0 on the shaft M by rods P similar to those'I.When the brake is released, these shoes are removed from the wheels bymeans of a spring, T, connecting an arm, T, on the rockshaft to theframe of the runninggear.

In order that the brakes of other cars may be controlled by themechanism on this car, 8 5 the rod B is connected to thelever G, asstated, and the lever is provided with rods extending toward therespective ends of the car, and provided with hooks on their ends forthe attachment of the ordinary brake-rods of other 0 cars. This lever isprovided with a spring, 0 by which the shoes on the other cars areremoved from the carwheels' when the brake is released.

I claim as my invention- 1. In a car-brake, the combination, with theshoes, of the pull-rod D, lever D, to which the rod is secured, clip Darm E, rock-shaft F, and connection between the rock-shaft andbrake-shoes, substantially as set forth. IOO

2. Inabrake,the combination, with the shoes, of the pull-rod D, lever D,to which one end of the rod is secured, clips D and K, spring J, arm E,rock-shaft F, and connection between the rock-shaft and shoes,substantially as set forth.

3. In abrake,thecombinati0n,with the shoes, of the pullrod D, lever D,clip D arm E, rock-shaft to which the arm is secured, c011- nectionbetween the rock-shaft and shoes at one end of the car, and connectionbetween the lever and shoes at the other end of the car, substantiallyas set forth.

4. Inabrake,tl1e c0mbinati0n,with the shoes, of the pull-rod D, lever D,clip D", arm E, 15 rock-shaft F, to which the arm is secured, connectionbetween the rock-shaft and shoes at one end of the car, rod N, arm M, towhich the lever D is connected by the rod N, rock-shaft M, connectionbetween the rock-shaft and 20 shoes, and spring '1, connecting therock-shaft to the running-gear, substantially as set forth.
